Loveholidays review: Holiday nightmare - flight cancelled (vulnerable children at home)

Urgent Complaint Regarding Flight Change and Resulting Disruption – Booking via Loveholidays
Dear SunExpress Holidays Customer Service,
My name is Jason O'Connell, and I am writing to formally raise a complaint regarding a significant disruption to our recent holiday plans caused by a change to our return flight.
We booked a 5-night stay in Kusadasi through Loveholidays on 2 January 2025, with travel dates from 11 April to 16 April 2025. However, we were recently informed by Loveholidays that SunExpress has unilaterally changed our return flight to 18 April 2025 — two days later than originally scheduled.
This unexpected change has caused considerable distress and financial strain for my family. We have four young children, including children with autism, who were being cared for by a carer during our absence. The extension of our trip has forced us to urgently arrange additional childcare, dog sitting, and accommodation in Kusadasi, all at our own expense. This was meant to be a much-needed respite for my wife, who is recovering from illness, and instead it has turned into a stressful and costly ordeal.

We are faced:
Additional accommodation costs for two nights
Extra airport transfer expenses
Increased childcare and pet care costs back home
Emotional strain on our family, particularly our children
Given the circumstances, I am requesting immediate clarification on the following:

Why was our return flight changed without our consent?
What compensation or support can SunExpress provide to cover the additional costs and inconvenience caused?
Who can we contact directly to resolve this matter promptly?

I would appreciate a swift response to this complaint, as we are still managing the consequences of this disruption.
Sincerely,
Jason O'Connell
